以下、本発明の実施形態について、適宜図面を参照しながら詳細に説明する。
図１は、本発明の一実施形態に係る空気調和機の室外機１００を斜め上方から見た前面斜視図である。
実施形態の空気調和装置は、室外機１００と室内機（図示せず）とが冷媒配管（図示せず）によって接続されている。これにより、冷凍サイクルが構成され、室内の空気調和が行われる。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
FIG. 1 is a front perspective view of an outdoor unit 100 for an air conditioner according to an embodiment of the present invention, viewed obliquely from above.
In the air conditioner of the embodiment, an outdoor unit 100 and an indoor unit (not shown) are connected by refrigerant pipes (not shown). Thereby, a refrigerating cycle is configured and indoor air conditioning is performed.

室外機１００は、筐体１内に圧縮機(図示せず)、熱交換器（図示せず）、減圧装置（図示せず）、送風器(図示せず)、および電気箱(図示せず)を備えている。 The outdoor unit 100 includes a compressor (not shown), a heat exchanger (not shown), a pressure reducing device (not shown), a blower (not shown), and an electric box (not shown) in the housing 1. ).

圧縮機、熱交換器、および減圧装置は冷凍サイクルを構成する。
送風器は、室外機１００の熱交換器周りの空気を外部空間に送り出し、熱交換を促進する。
電気箱は、室外機１００の制御を担う制御基板が搭載されている。制御基板には、表示部や各種スイッチなどの電気品(図示せず)が実装されている。 A compressor, a heat exchanger, and a pressure reducing device constitute a refrigeration cycle.
The air blower sends air around the heat exchanger of the outdoor unit 100 to the outside space to promote heat exchange.
The electric box is equipped with a control board that controls the outdoor unit 100 . Electrical components (not shown) such as a display and various switches are mounted on the control board.

図２は、室外機１００から筐体カバー２を外し、開口カバー蓋６を開けた状態を斜め上方から見た前面斜視図である。
室外機１００の前面下部は、下側キャビネット３が筐体１を形成している。
室外機１００の前面中央部には製品サービス時に、電気箱の内部の確認が出来るように取り外し可能な蓋状の筐体カバー２が筐体１の前面板１Ａに取り付け固定されている。前面板１Ａの下部は下側キャビネット３等で形成されている。 FIG. 2 is a front perspective view of the state in which the housing cover 2 is removed from the outdoor unit 100 and the opening cover lid 6 is opened, as viewed obliquely from above.
A lower cabinet 3 forms a housing 1 in the front lower portion of the outdoor unit 100 .
At the center of the front surface of the outdoor unit 100, a removable lid-like housing cover 2 is attached and fixed to the front plate 1A of the housing 1 so that the inside of the electric box can be checked during product service. The lower part of the front plate 1A is formed with a lower cabinet 3 and the like.

筐体カバー２の後方には、電気箱全体をカバーする電気箱カバー板４が固定されている。こうして、電気箱は制御基板８（図３参照）やその他の電気品(図示せず)保護のために電気箱カバー板４で覆われている。図３は、開口部５の周辺の前面拡大図である。 An electric box cover plate 4 that covers the entire electric box is fixed behind the housing cover 2 . Thus, the electrical box is covered with an electrical box cover plate 4 to protect the control board 8 (see FIG. 3) and other electrical items (not shown). FIG. 3 is an enlarged front view of the periphery of the opening 5. FIG.

電気箱カバー板４は、前面板１Ａである下側キャビネット３より奥方に配置されている。つまり、電気箱カバー板４は下側キャビネット３を含む前面板１Ａより奥側に凹んで設置されている。
筐体カバー２は、前面視で、電気箱全体をカバーする面積を有している。 The electric box cover plate 4 is arranged behind the lower cabinet 3, which is the front plate 1A. In other words, the electric box cover plate 4 is recessed inward from the front plate 1A including the lower cabinet 3. As shown in FIG.
The housing cover 2 has an area that covers the entire electric box when viewed from the front.

電気箱カバー板４の右下部には、弱電部８Ｊの電気品を点検するための開口部５が設けられている。これにより、開口部５から電気箱の内部に配置された制御基板８の一部（弱電部品が実装される弱電部８Ｊ等）を目視できる。 An opening 5 is provided in the lower right portion of the electrical box cover plate 4 for inspecting the electrical components of the low current section 8J. As a result, a part of the control board 8 arranged inside the electric box (such as the light current section 8J on which the light current component is mounted) can be seen through the opening 5 .

そして、開口部５を開閉するための開口カバー蓋６が電気箱カバー板４に設置されている。具体的には、開口カバー蓋６は電気箱カバー板４に設けられるヒンジ７にて、回転自在に支持されている。 An opening cover lid 6 for opening and closing the opening 5 is installed on the electric box cover plate 4 . Specifically, the opening cover lid 6 is rotatably supported by a hinge 7 provided on the electric box cover plate 4 .

ところで、室外機１００は、屋外で使用されるため、風雨に晒される。そのため、室外機１００の筐体１は耐候性や所定の強度が必要である。そこで、筐体１、電気箱カバー板４、および開口カバー蓋６は耐候性や強度が高い板金製としている。なお、筐体１、電気箱カバー板４、および開口カバー蓋６が所定の耐候性や強度を有すれば、板金以外の材料を用いてもよい。 By the way, since the outdoor unit 100 is used outdoors, it is exposed to wind and rain. Therefore, the housing 1 of the outdoor unit 100 requires weather resistance and predetermined strength. Therefore, the housing 1, the electric box cover plate 4, and the opening cover lid 6 are made of sheet metal having high weather resistance and strength. Materials other than sheet metal may be used as long as the housing 1, the electric box cover plate 4, and the opening cover lid 6 have predetermined weather resistance and strength.

前記したように、開口カバー蓋６は、電気箱カバー板４のヒンジ７により、開閉自在に取り付けられている。開口カバー蓋６は、ヒンジ７を中心に９０度以上回転して下側に開く（図２、図３参照）。開口カバー蓋６を下側に開くことで、利用者は、開口部５を通して制御基板8の弱電部８Ｊを目視できる。 As described above, the opening cover lid 6 is attached to the electric box cover plate 4 by the hinge 7 so as to be openable and closable. The opening cover lid 6 rotates about the hinge 7 by 90 degrees or more and opens downward (see FIGS. 2 and 3). By opening the opening cover lid 6 downward, the user can see the weak current section 8J of the control board 8 through the opening 5. As shown in FIG.

制御基板８の弱電部８Ｊには、現地施工時に選択する必要のある設定、或いは、特別に作動させたい機能を設定したりするのに必要なディップスイッチが装備されている。また、サービス作業時に空気調和装置の運転状態等が確認できるように７セグメントＬＥＤが制御基板８上に装備されている。 The light current section 8J of the control board 8 is equipped with DIP switches necessary for setting necessary to be selected at the time of on-site installation or for setting functions to be specially operated. Also, a 7-segment LED is provided on the control board 8 so that the operating state of the air conditioner can be checked during service work.

このように、開口カバー蓋６を下側に開くことで、利用者は、ディップスイッチや７セグメントＬＥＤを開口部５から目視できる。これにより、開口カバー蓋６を開くことで、利用者のサービスマンは電気カバー４を開くことなく、ディップスイッチや７セグメントＬＥＤにアクセスが可能である。 By opening the opening cover lid 6 downward in this way, the user can see the DIP switches and the 7-segment LED through the opening 5 . As a result, by opening the opening cover lid 6 , the user's service person can access the DIP switches and the 7-segment LED without opening the electric cover 4 .

某国には、メンテナンス等を行うサービスマンの作業時の安全性を確保するために、安全基準が規定されている。
この安全基準によれば、室外機１００の電気箱内を通電状態で操作する場合には、帯電防止仕様の全身つなぎ・ゴム手袋・皮手袋・顔面保護シールドのついたヘルメットを装着する必要がある。サービスマンの防護用具への着換えは大掛かりとなる。そのため、作業性も悪く、作業時間の増加にもつながる。そこで、防護用具への着換えはサービスマンから疎まれていた。 In a certain country, safety standards are stipulated in order to ensure the safety of service personnel who perform maintenance and the like during work.
According to this safety standard, when operating the electric box of the outdoor unit 100 in a energized state, it is necessary to wear an antistatic full-body coverall, rubber gloves, leather gloves, and a helmet with a face protection shield. . Changing service personnel into protective gear is a big deal. As a result, workability is poor, leading to an increase in work time. Therefore, changing into protective equipment was disliked by service personnel.

本実施形態の構成によれば、開口カバー蓋６を弱電部８Ｊが目視できる開口部５を開閉できる位置に設けることで、開口カバー蓋６を開けた際、開口部５から露出するのは弱電部８Ｊだけとなる。
そのため、弱電部８Ｊに対する作業を行う際に開口カバー蓋６を開ければ済むので、防護用具の装着は不要となる。 According to the configuration of the present embodiment, the opening cover lid 6 is provided at a position where the opening 5 can be opened and closed so that the weak current portion 8J can be seen. Part 8J only.
Therefore, since it is sufficient to open the opening cover lid 6 when performing work on the weak current section 8J, it is not necessary to wear a protective tool.

＜開口カバー蓋６＞
図４に開口カバー蓋６の近傍の図３のＩ－Ｉ断面を示す。図５に開口カバー蓋６が開口部５を閉じた際の開口カバー固定ネジ９の周辺を拡大した図３のＩ－Ｉ断面相当図を示す。
開口カバー蓋６の一方端部は、ヒンジ７を介して電気箱カバー板４に回転自在に軸支されている。 <Opening cover lid 6>
FIG. 4 shows the II section of FIG. 3 in the vicinity of the opening cover lid 6. As shown in FIG. FIG. 5 shows an enlarged view of the area around the opening cover fixing screw 9 when the opening cover lid 6 closes the opening 5, corresponding to a sectional view taken along line II of FIG.
One end of the opening cover lid 6 is rotatably supported by the electric box cover plate 4 via a hinge 7 .

開口カバー蓋６の他方端部には、開口カバー固定ネジ９が挿通するネジ挿通孔６ａ（図４、図５参照）が設けられている。開口カバー蓋６のネジ挿通孔６ａには、ワッシャｗ１を挿通して開口カバー固定ネジ９のねじ部９ｏが挿通される。そして、図４に示すように、ねじ部９ｏの先端側からセムスワッシャー１０が開口カバー蓋６近くまで嵌め込まれている。 The other end of the opening cover lid 6 is provided with a screw insertion hole 6a (see FIGS. 4 and 5) through which the opening cover fixing screw 9 is inserted. The screw portion 9o of the opening cover fixing screw 9 is inserted through the screw insertion hole 6a of the opening cover lid 6 through the washer w1. Then, as shown in FIG. 4, the sems washer 10 is fitted from the tip side of the threaded portion 9o to the vicinity of the opening cover lid 6. As shown in FIG.

セムスワッシャー１０が開口カバー蓋６を挟んで、開口カバー固定ネジ９のねじ部９ｏに取り付けられることで、図４に示すように、開口カバー蓋６を開いた際にもセムスワッシャー１０が開口カバー固定ネジ９の開口カバー蓋６からの抜け止めとなる。そのため、開口カバー蓋６のネジ挿通孔６ａから開口カバー固定ネジ９が抜けることが抑制される。 By attaching the sems washer 10 to the screw portion 9o of the opening cover fixing screw 9 with the opening cover lid 6 interposed therebetween, as shown in FIG. It prevents the fixing screw 9 from coming off from the opening cover lid 6 . Therefore, the opening cover fixing screw 9 is prevented from coming out of the screw insertion hole 6 a of the opening cover lid 6 .

一方、電気箱カバー板４には、開口カバー固定ネジ９のねじ部９ｏが螺合される雌ねじ４ｍが形成されている。雌ねじ４ｍは電気箱カバー板４をバーリング加工することにより形成してもよいし、雌ねじ４ｍが形成された円柱形状の部品を電気箱カバー板４に溶接してもよく、電気箱カバー板４に開口カバー固定ネジ９が螺着される雌ねじ４ｍが形成されれば、構成は任意に選択できる。開口カバー蓋６を開ける際には、図２に示すように、筐体カバー２を外した状態で、開口カバー固定ネジ９（図５参照）を緩め、開口カバー蓋６を下側に開く（図２、図３参照）。 On the other hand, the electric box cover plate 4 is formed with a female screw 4m into which the threaded portion 9o of the opening cover fixing screw 9 is screwed. The female thread 4m may be formed by burring the electrical box cover plate 4, or a columnar part having the female thread 4m may be welded to the electrical box cover plate 4. The configuration can be arbitrarily selected as long as the female screw 4m into which the opening cover fixing screw 9 is screwed is formed. When opening the opening cover lid 6, as shown in FIG. 2, with the housing cover 2 removed, loosen the opening cover fixing screw 9 (see FIG. 5) and open the opening cover lid 6 downward ( 2 and 3).

室外機１００の使用時には、図５に示すように、開口カバー蓋６に取り付けられた開口カバー固定ネジ９が、電気箱カバー板４の雌ねじ４ｍに螺合され、開口カバー蓋６で開口部５を閉じた状態にある。そして、図１に示すように、筐体カバー２が前面板１Ａにねじｎ１止め等で取り付けられている。そのため、開口部５は、開口カバー蓋６と筐体カバー２とで二重にカバーされている。 When using the outdoor unit 100, as shown in FIG. closed. Then, as shown in FIG. 1, the housing cover 2 is attached to the front panel 1A with screws n1 or the like. Therefore, the opening 5 is doubly covered with the opening cover lid 6 and the housing cover 2 .

＜開口部５を通じての弱電部８Ｊの作業＞
図６は、室外機１００から筐体カバー２を外した状態を斜め前上方から見た前面斜視図である。
室外機１００の据え付け、メンテナンスに際しては、室外機１００（図１参照）の前側の固定ねじｎ１を緩めて筐体カバー２の上部側の係合を外し、筐体カバー２を前面板１Ａから外す。 <Working on the weak current section 8J through the opening 5>
FIG. 6 is a front perspective view of the state in which the housing cover 2 is removed from the outdoor unit 100, viewed obliquely from the front upper side.
When installing and maintaining the outdoor unit 100, loosen the fixing screw n1 on the front side of the outdoor unit 100 (see FIG. 1) to disengage the upper side of the housing cover 2, and remove the housing cover 2 from the front panel 1A. .

続いて、図５に示す開口カバー固定ネジ９を緩めて、図４に示すように、開口カバー蓋６を手前側に１８０度回転させて開け、開口部５を外側から目視できる状態とする。 Subsequently, the opening cover fixing screw 9 shown in FIG. 5 is loosened, and the opening cover lid 6 is opened by rotating it 180 degrees toward the front side as shown in FIG. 4 so that the opening 5 can be viewed from the outside.

この際、開口カバー蓋６は、電気箱カバー板４より前側に配置される下側キャビネット３と接触するため、電気箱カバー板４が延在する面４ｐに対して１８０度未満の所定角度θ１までしか開かない。そのため、開口カバー蓋６は下側キャビネット３より前側に突き出た状態となる。 At this time, since the opening cover lid 6 comes into contact with the lower cabinet 3 arranged on the front side of the electric box cover plate 4, it is formed at a predetermined angle θ1 of less than 180 degrees with respect to the surface 4p on which the electric box cover plate 4 extends. only open up to Therefore, the opening cover lid 6 protrudes forward from the lower cabinet 3 .

そのため、開口カバー蓋６を閉じ忘れた状態で、筐体カバー２を閉じようとしても、下側キャビネット３より前側に突き出た開口カバー蓋６と当接（干渉）するため、筐体カバー２を閉じることができない。すなわち、開口カバー蓋６を閉め忘れた場合、筐体カバー２を閉じることができないこととなる。これにより、開口カバー蓋６の閉め忘れを抑制できる。 Therefore, even if the housing cover 2 is attempted to be closed in a state in which the opening cover lid 6 has been forgotten to be closed, the housing cover 2 abuts (interferes) with the opening cover lid 6 protruding forward from the lower cabinet 3 . cannot be closed. That is, if the opening cover lid 6 is forgotten to be closed, the housing cover 2 cannot be closed. Thereby, forgetting to close the opening cover lid 6 can be suppressed.

この構成を実現するため、開口部５は電気箱カバー板４の左右あるいは下側に寄った位置とし、開口カバー蓋６を開けた際に開口カバー蓋６が、電気箱カバー板４より前側に配置される下側キャビネット３や右側キャビネット３ｍまたは左側キャビネット３ｈに当接する構成とする（詳細は後記）。 In order to realize this configuration, the opening 5 is positioned to the left, right, or lower side of the electric box cover plate 4, and when the opening cover lid 6 is opened, the opening cover lid 6 is positioned forward of the electric box cover plate 4. It is configured to contact the lower cabinet 3, the right cabinet 3m, or the left cabinet 3h (details will be described later).

なお、開口カバー蓋６を開けた際、開口カバー固定ネジ９は、開口カバー蓋６につけたままとする。前記したように、セムスワッシャー１０を、開口カバー蓋６をはさむように開口カバー固定ネジ９に取り付けることにより、ネジ落下抑制を図れる。 When the opening cover lid 6 is opened, the opening cover fixing screw 9 is left attached to the opening cover lid 6. - 特許庁As described above, by attaching the sems washer 10 to the opening cover fixing screw 9 so as to sandwich the opening cover lid 6, the drop of the screw can be suppressed.

これに反して、セムスワッシャー１０を設けない場合、開口カバー蓋６を開けた際に開口カバー固定ネジ９が開口カバー蓋６から外れてしまう。そのため、サービスマンは開口カバー固定ネジ９を探す手間が発生する場合がある。
